Abstract

An installation for the removal of oil slicks on expanses of water is used to burn away the oil film. For this, a number of porous shaped bodies (2, 3, 4) made from a fireproof, inorganic and ceramic fibre material are connected together. Each shaped body (2, 3, 4) is made to float by hydrophobic treatment.

Description

Einrichtung zur Beseitigung von Ölfilmen auf Gewässern Device for removing oil films on water
Die Erfindung betrifft eine Einrichtung zur Beseitigung von Ölfilmen auf Gewässern.The invention relates to a device for removing oil films on water.
Beim Leckwerden von Tankschiffen oder Bohrinseln bilden sich auf dem Meer bzw. Flüssen, Kanälen oder Seen Ölfilme. Diese führen zu beträchtlichen Umweltschäden. Dies insbesondere, wenn sie an die Küste bzw. Ufer gelangenWhen tankers or oil rigs leak, oil films form on the sea or rivers, canals or lakes. This leads to considerable environmental damage. This is especially true when they reach the coast or shore
Zur Beseitigung von Ölfilmen werden Spezialschiffe eingesetzt, die den Ölfilm absaugen sollen. Der Wirkungsgrad einer solchen ölabsaugung ist niedrig.Special vessels are used to remove oil films, which are intended to extract the oil film. The efficiency of such an oil extraction is low.
Um die Ausbreitung von Ölfilmen zu begrenzen, sind Kunststoffbarrieren üblich. Diese haben sich bei Seegang bzw. stärkeren Wasserbewegungen als wenig geeignet gezeigt. Sie tragen auch nichts zur Beseitigung des Ölfilms bei.Plastic barriers are common to limit the spread of oil films. These have been shown to be unsuitable when the sea is swell or the water moves heavily. They also do nothing to remove the oil film.
Es wurde auch versucht, Ölfilme durch Abfackeln zu beseitigen. Nachteilig ist dabei, daß schwer entzündbare Ölfilme leicht wieder erlöschen.Attempts have also been made to remove oil films by flaring. The disadvantage here is that oil films that are difficult to ignite easily go out again.
Aufgabe der Erfindung ist es, eine Einrichtung der eingangs genannten Art vorzuschlagen, mit der sich der Ölfilm abbrennen läßt. Erfindungsgemäß ist obige Aufgabe bei einer Einrichtung der eingangs genannten Art dadurch gelöst, daß mehrere poröse Formkörper aus einem feuerfesten, anorganischen, keramischen Fasermaterial miteinander verbunden sind und daß jeder Formkörper durch eine Hydrophobierung schwimmfahig ist.The object of the invention is to propose a device of the type mentioned at the beginning with which the oil film can be burned off. According to the invention, the above object is achieved in a device of the type mentioned at the outset in that a plurality of porous molded articles made from a refractory, inorganic, ceramic fiber material are connected to one another and in that each molded article is floatable through hydrophobization.
Die Formkörper werden auf oder um den Ölfilm ausgelegt oder vorsorglich zum Schütze einer Anlage vor einem Küsten- bzw. Uferabschnitt ausgelegt. Durch die Hydrophobierung schwimmen die Formkörper. Aufgrund ihrer Porosität üben sie auf öl eine starke kapillare Aufsaugwirkung aus. So ölgetränkte Formkörper lassen sich leicht entzünden. Das aufgesaugte öl brennt dann ab, ohne daß der Formkörper selbst mitverbrennt oder geschädigt wird. Er saugt ständig öl des Ölfilms nach. Die Formkörper wirken also nach Art eines Dochtes für den Ölfilm.The moldings are laid out on or around the oil film or, as a precautionary measure, to protect a system from a coastal or bank section. The moldings float due to the hydrophobization. Due to their porosity, they exert a strong capillary suction effect on oil. Moldings soaked in oil can easily ignite. The absorbed oil then burns without the molded body itself being burned or damaged. It constantly sucks up oil from the oil film. The shaped bodies thus act like a wick for the oil film.
Um zu vermeiden, daß sich die Verbindung der Formkörper beim Abbrennen des Öles löst, sind die Formkörper in Ausgestaltung der Erfindung mit einer unverbrennbaren Schnur oder einem hitzebestandigen Draht verbunden.In order to avoid that the connection of the shaped bodies is released when the oil burns off, the shaped bodies are connected in an embodiment of the invention with an incombustible cord or a heat-resistant wire.
In Weiterbildung der Erfindung sind die Formkörper durch eine Tränkung mit einem Silikonöl oder einem Silikonharz hydrophobiert. Die Formkörper schwimmen damit ohne weiteres.In a further development of the invention, the shaped bodies are made hydrophobic by impregnation with a silicone oil or a silicone resin. The molded bodies thus float easily.
Die Formkörper können von genadelten Matten (Blankets) aus keramischen Fasern gebildet sein. Als Formkörper eignen sich auch Platten aus Fasermaterial .The shaped bodies can be formed from needled mats (blankets) made of ceramic fibers. Sheets of fiber material are also suitable as shaped bodies.
In einer anderen Ausgestaltung der Erfindung sind die Formkörper von Rohrstücken gebildet, die zur Verbindung auf eine Schnur oder einen Draht aufgefädelt sind. Eine solche Formkörperkette eignet sich insbesondere zum vorsorglichen Schutz von Küsten- oder Uferzonen gegen eine ölverschmutzung. Die Formkörper werden dann entzündet, wenn ein antreibender Ölfilm festgestellt ist.In another embodiment of the invention, the shaped bodies are formed from pipe pieces which are threaded onto a cord or a wire for connection. Such a chain of shaped articles is particularly suitable for the precautionary protection of coastal or riparian zones against oil pollution. The moldings are ignited when a driving oil film is found.

Ausgangsmaterial für die in den Fig. 1 bis 3 dargestellten Formkörper, nämlich die Matte 1, die Platten 2, 3 und 4 und das Rohrstück 5 ist ein feuerfestes, anorganisches Fasermaterial, das beispielsweise aus 47 % Aλ ~<D~ und 53 % S\ Q- besteht. Die Formkörper sind porös. Sie sind mit einem Sili¬ konöl oder einem Silikonharz hydrophobiert, so daß sie schwimmfähig sind.The starting material for the shaped bodies shown in FIGS. 1 to 3, namely the mat 1, the plates 2, 3 and 4 and the pipe section 5 is a refractory, inorganic fiber material which, for example, consists of 47% Aλ ~ <D ~ and 53% S \ Q- exists. The moldings are porous. They are hydrophobized with a silicone oil or a silicone resin, so that they are buoyant.
Die Matte 1 ist durch Nadeln des Fasermaterials hergestellt. Ihre Länge liegt zwischen 1 m und 20 m. Ihre Breite beträgt 0,2 m bis 1,0 . Ihre Dicke liegt zwischen 1 cm und 10 cm. Mehrere der Matten 1 sind mittels einer nicht brennbaren Schnur aus keramischen Fasern zu einer größeren Fläche verbunden. Eine solche Schnur ist in den Fig. 2 und 4 dargestellt. Die Matte 1 ist flexibel, so daß sie sich beim Schwimmen Wellen der Wasseroberfläche anpaßt.The mat 1 is produced by needling the fiber material. Their length is between 1 m and 20 m. Their width is 0.2 m to 1.0. Their thickness is between 1 cm and 10 cm. Several of the mats 1 are connected to a larger area by means of a non-combustible cord made of ceramic fibers. Such a cord is shown in FIGS. 2 and 4. The mat 1 is flexible so that it adapts to waves of the water surface when swimming.
Die Platten 2, 3 und 4 sind aus dem Fasermaterial beispielsweise durch Pressen hergestellt. Sie sind im wesentlichen starr. Ihre Länge liegt zwischen 0,2 m und 2,0 m. Ihre Breite beträgt 0,2 m bis 1,0 m. Ihre Dicke liegt zwischen 1 cm und 10 cm.The plates 2, 3 and 4 are made of the fiber material, for example by pressing. They are essentially rigid. Their length is between 0.2 m and 2.0 m. Their width is 0.2 m to 1.0 m. Their thickness is between 1 cm and 10 cm.
Beim Ausführungsbeispiel nach Fig. 2 sind die unterschiedlich langen Plat¬ ten 2, 3 und 4 mit Schnüren 6 verbunden. Die Schnüre 6 sind aus feuer¬ festem, anorganischem Fasermaterial hergestellt. Durch die Schnurverbindung ist das aus mehreren Platten 2, 3 und 4 bestehende Gebilde ebenfalls flexi¬ bel, so daß es sich einer Wellenbewegung der Wasseroberfläche anpaßt. Das Rohrstück 5 weist eine Länge zwischen 0,1 m und 1,0 m auf. Sein Innen¬ durchmesser beträgt 0,1 m bis 1,0 m, wobei sein Außendurchmesser zwischen 0,12 m und 1,30 m liegt. Eine Vielzahl solcher Rohrstücke 5 ist auf eine flexible Schnur 7 aus einem hitzebeständigen, keramischen Fasermaterial aufgefädelt (vgl. Fig. 4). An den Enden der Schnur 7 ist eine Öse 8 zur Verankerung ausgebildet. Die Schnur 7 mit den Rohrstücken 5 läßt sich um eine zu schützende Anlage verlegen.In the embodiment according to FIG. 2, the plates 2, 3 and 4 of different lengths are connected with cords 6. The cords 6 are made of refractory, inorganic fiber material. Due to the cord connection, the structure consisting of several plates 2, 3 and 4 is also flexible, so that it adapts to a wave movement of the water surface. The pipe section 5 has a length between 0.1 m and 1.0 m. Its inner diameter is 0.1 m to 1.0 m, its outer diameter being between 0.12 m and 1.30 m. A large number of such tube pieces 5 are threaded onto a flexible cord 7 made of a heat-resistant, ceramic fiber material (cf. FIG. 4). At the ends of the cord 7, an eyelet 8 is formed for anchoring. The cord 7 with the pipe pieces 5 can be laid around a system to be protected.
Kommt ein Ölfilm mit den Formkörpern 1 bis 5 in Berührung, dann saugen diese aufgrund der Kapillarwirkung ihrer Poren öl auf. Dieses ist dann in den Formkörpern 1 bis 5 fein verteilt, die ölgetränkten Formkörper 1 bis 5 lassen sich leicht entzünden. Dabei brennt das öl ab, ohne daß die Formkörper 1 bis 5 oder die Schnur 6, 7 mit abbrennen. Beim Abbrennen des Öls saugen die Formkörper 1 bis 5 aus dem Ölfilm ständig öl nach, so daß ein kontinuierlicher Abbrand des Öles erfolgt.If an oil film comes into contact with the shaped bodies 1 to 5, they absorb oil due to the capillary action of their pores. This is then finely distributed in the moldings 1 to 5, the oil-soaked moldings 1 to 5 can be easily ignited. The oil burns off without the shaped bodies 1 to 5 or the cord 6, 7 also burning off. When the oil burns off, the moldings 1 to 5 continuously suck in oil from the oil film, so that the oil burns off continuously.
Nach der Beseitigung des Ölfilms lassen sich die Formkörper 1 bis 5 weiterverwenden. After the removal of the oil film, the moldings 1 to 5 can be reused.
